Presentation Outline

Brazilian Agricultural Zoning

Agrometeorological operational systems in Brazil – regional and national

Effects of climate change (IPCC) in Brazilian Agricultural Zoning


Agricultural Zoning

Agribusiness GDP in 2003: US$ 165 billion (30% GDP - US$ 500 billion)

Agribusiness Exportations: US$ 30 billion (40%) 30% of jobs Grain production in 2003: 122 millions tons

Program coordinated by the Department of Agriculture and EMBRAPA (National Institute for Agricultural Research) since 1995

Federal Farm Credit PolicyUS$ 8 billion (US$ 2.5 billion for small farmers)


Main Objective Decrease the climate risks

dry spells during flowering and grain-filling (60%) excessive rain during the harvest period (30%)

Product

Planting Calendars

Crops: Corn, Soybean, Beans, Rice (Wheat, Sorghum,

Fruits, Coffee)

Periods: Dekad (10 days), Oct to Dec (Jan to Dec)

Counties / Municipal districts

Macro-regions: Central, Southeast and South

(Northeast)

Risk: less than or equal to 20%

Methodology

Simulation of cumulative water balance for different soil types, planting dates, cycle lengths, ground stations

Decision criteria / Risk Analysis:a) WRSI during reproductive stage Threshold Value

(80% of all simulated years) WRSI: Water Requirement Satisfaction IndexWRSI = actual / maximum evapotranspiration

b) Excessive rain during harvest50mm accumulated in 3 days of a 5-days period


Preliminary Data Collection

Results

Organization of federal farm credit policy and

insurance

Decrease of agricultural losses due to climate events

(Insurance debt = US$ 637 million accumulated in 5

years)

Even self-financed farmers are using the zoning

Increase: productivity, production and use of

technology

Losses of US$ 33 millions in 2002: farmers growing

corn during fall and winter in unsuitable (high risk)

areas

Frauds decrease and inhibition

Availability of data for agricultural planning

Demand for new crops, regions and periods


Questions

What can happen to agricultural zoning in next decades ?

Will the suitable areas change in the case of new climate conditions ? (decrease ?, increase ?, migrate ?)

Methodology

Prepare new zonings simulating different climate conditions according to IPCC report (2001)

Climate scenarios: Current, Increase of 1°C, 3°C and 5.8°C in Temperature and Increase of 15% in precipitation


Climate Conditions Suitable for Coffee Production

Average Annual Temperature: 18°C to 22°C (up to 23°C)

Annual Water Deficit: 0mm to 100mm (up to 150mm)

Absolute Minimum Temperature: > 1°C (Frost Risk)


Total Area: 249.000km2


Further Works

Simulations for other crops

Simulations for other states

Use of other models and analysis of climate

change
